Or you can just make your own with threaded rod, carbon fiber tubing and a couple of 4-40 nuts. You won't have the reverse threads on one end but you may have a stiffer pushrod when completed ... at a lower cost. You can also make them any length you want.

I like the Hanger 9 Pro Links or similar products from other vendors and use them from time to time but more often, I just make my own.
